ABSTRACT:
A tufting machine with two rows of needles may be mounted staggered relative to each other on a single needle bar is provided with a single row of loopers cooperable with either or both rows of needles. The rows of needles are longitudinally spaced by a relatively narrow distance. Hollow ground loopers are used in conjunction with maximum target area needles and a needle plate with a serrated edge rather than needle plate fingers, to improve the operation of the tufting machine, particularly when the rows of needles are spaced transversely at a relatively fine gauge. This permits the efficient operation of a fine gauge tufting machine in which rows of needles can be shifted in distances of the composite needle gauge thereby improving finish, reducing backstitch yarn, increasing machine speed, and even reducing wasted face yarn when used with fixed yarn feed mechanisms.
